The master password dialog is not well labeled. Any chance it could be spoofed using JS and someone could then access all passwords?
IMO, the master password request dialog is not well labeled, and its identity (and authenticity) seem a little in doubt each time it appears. It is possible someone could be spoof it using JS and I could unwittingly hand my "skeleton key" over to a thief? Please tell me I am just being paranoid!

I don't think a script in an ordinary web page has permission to read your passwords for other websites, even if you do not use a master password. It should be restricted to seeing what the password manager populates into the page.
For that reason, even if a page captured your master password, I don't think it could use it in a nefarious way. But perhaps I'm insufficiently devious.

That's good to hear. Thanks. Nevertheless, although admittedly less important, I think the master password dialog should be less cryptic. Currently it says "Password Required" in the title, and "Please enter the master password for the Software Security Device" in the dialog itself. Perhaps "Firefox requires your master password to enable Sync"?
Thanks for your help and consideration.
That might be clearer! You can submit suggestions for features changes using

You can also consider to set the signon.autofillForms to false on the about:config page to prevent Firefox from entering a name and password automatically.
